tty: n_gsm: add copyright Siemens Mobility GmbH
More than 1/3 of the n_gsm code has been contributed by us in the last 1.5 years, completing conformance with the standard and stabilizing the driver: - added UI (unnumbered information) frame support - added PN (parameter negotiation) message handling and function support - added optional keep-alive control link supervision via test messages - added TIOCM_OUT1 and TIOCM_OUT2 to allow responder to operate as modem - added TIOCMIWAIT support on virtual ttys - added additional ioctls and parameters to configure the new functions - added overall locking mechanism to avoid data race conditions - added outgoing data flow to decouple physical from virtual tty handling for better performance and to avoid dead-locks - fixed advanced option mode implementation - fixed convergence layer type 2 implementation - fixed handling of CLD (multiplexer close down) messages - fixed broken muxer close down procedure - and many more bug fixes With this most of our initial RFC has been implemented. It gives the driver a quality boost unseen in the decade before. Add a copyright notice to the n_gsm files to highlight this contribution.
